NONFREEZING RADIATOR.

Application led August 17, 1922. Serial No. 582,398.

To all whom it may concern:

Vculate through the radiator and Be it known that GEORGE E. WALTER, a

citizen of the United States, residingv atl in the county of Fountain and Statev Gates, of Indiana, has invented certain new and useful Improvements in Nonfreezing Radiators, of which the following is a. specification.

My invention relates to automobile radiators and its principal object is to provide a radiator which will not freeze in cold weather. y

A further object of the invention-4 is to provide a radiator for automobiles embodying a number of radiator tube sections or units, one of which being of a relatively small bore for use in normal or moderate weather and the other being of a relatively large bore for use in cold weather so that a maximum circulation of hot water will cirthereby obviate freezing of the latter.

It is also an object of the invention to provide an automobile radiator employing a number of units and which are so constructed as to be readily disassembled so as to connect either one of the units up with the water system.

Vith the preceding and other objects and advantagesl in mind, the invention consists in the novel combination of elements construction andarrangement of parts in operation as to be hereinafter fully enlarged upon, claimedand illustrated in the accompanying drawing, wherein- K Figure 1 is a front elevation ofa radiator constructed in tion. n

Figure 2 is a vertical sectional view of the same.

Figure 3 is a horizontal sectional view taken on lines 3-3 of Fig. l.

Figure t is a horizontal sectional view taken on lines 4t of Fig. 1.

Referring to the drawing in detail wherein like characters of reference designate like parts throughout the several views, the numeral 5 designates the radiator casing which is made in sections 6 and 7 belted together as at 8. The upper section 6 is provided with a water reservoir 9 at its upper end while a water space or reservoir 10 is provided between the adjacent ends of the radiator sections.

Removably mounted in the casing 6 is a accordance with my inven-k radiator unit comprising conduits 12 of relatively small diameter adapted to be connected with the water cooling system of the automobile, not shown, in any desired manner. This radiator unit l2-is adapted to be used in moderate weather and normally cools the Water supply.

Removably arranged inthe casing section is a radiator section 13 comprising tubes 14 of a. greater diameter thanthe tubes 1'2 and vwhen directly connected with the water cooling supply causes a maximum amount of water to circulate to maintain a higher tem- 'perature in the radiator section and thereby obviate freezing of the latter. When it is desired to use the radiator section 13 the section-12 is disconnected and this section 13K connected with the water supply in the usual manner.

The radiator sections '12 and 13 are held rigidly in the casing sections 6 and 7 by V-shaped braces which are arranged in opposed relation and have their opposite ends connected with the walls of the casing sections.

Moreover, the interior of the radiator may be readily reached by detaching the sect-ions 6 and 7 for the purpose of repairing either one of the radiator units.

Thilo I have shown the preferred embodiment of the inventionv it will be understood that the invention may be embodied in other constructions and'that my limits of modifica-tions are only governed by what is What Iclaim as new and desire to secure by Letters Patent is y An automobile radiator comprising a cas'- ing, ya pair of radiator sections disposed in said casing one above the other in vertical alignment, each of said sections being pro` vided with Water tubes, the tubes of the upper section bei-ng of sn'lallcr diameter than the tubes of the lower section, water reservoirs disposed at the top and bottom of the casing, in cominunication respectively with the upper and lower radiator sections, an additional Water reservoir disposed in the casing intermediate of said radiator 'sections and communicating therewith, and water supply and exhaust pipes for said radiator sections.

In testimony whereof I atix my signature.

GEORGE E. WALTER. A
